OSHA #511 Occupational Safety and Health Standards for General Industry course

What type of guard is designed to move with the machine's operation?

1. Fixed Guard

2. Adjustable Guard

3. Self-Adjusting Guard

4. Interlocking Guard

The correct answer is: Self-Adjusting Guard

The type of guard designed to move with the machine's operation is a self-adjusting guard. This type of guard functions dynamically, adjusting automatically based on the position of the machinery and the materials being processed. Self-adjusting guards are particularly effective in ensuring operator safety while allowing for the necessary movement and operation of the machinery. They provide continuous protection by adapting as the machine operates, which minimizes the risk of contact with moving parts. Fixed guards, on the other hand, do not move and are permanently attached to the machine. They provide a stable, continuous barrier but are not suited for applications where the machine's configuration changes. Adjustable guards can be manually set to different positions, but they require human intervention to change their placement, which may compromise safety if not adjusted properly. Interlocking guards are designed to shut down the machine when the guard is opened, providing a safety measure when maintenance or adjustments are being made, but they do not move with the machine operation itself. Understanding these differences highlights the unique role of self-adjusting guards in maintaining safety while allowing for operational flexibility.
